fix: decode +AIDC data when dataToggle=1 (case-sensitivity bug)

dannyhaak · claude · dannyhaak · commit 623169f7d497 · 2026-02-26T15:42:27.000+01:00
The AIDC decode check looked for "datatoggle" (lowercase) but the
field name from scheme definitions is "dataToggle" (camelCase).
Dictionary lookup is case-sensitive, so AIDC data was never decoded.
